Debian Security Advisory DSA-3307-1 [email protected]
https://www.debian.org/security/ Alessandro Ghedini

Package : pdns-recursor
CVE ID : CVE-2015-1868

Toshifumi Sakaguchi discovered that the patch applied to pdns-recursor,
a recursive DNS server, fixing CVE-2015-1868, was insufficient in some
cases, allowing remote attackers to cause a denial of service
(service-affecting CPU spikes and in some cases a crash).

For the stable distribution (jessie), this problem has been fixed in
version 3.6.2-2+deb8u2.

For the testing distribution (stretch), this problem has been fixed
in version 3.7.3-1.

For the unstable distribution (sid), this problem has been fixed in
version 3.7.3-1.

We recommend that you upgrade your pdns-recursor packages.
